I have a Multiplus II 3kVA 230V. I've been camping in my RV off-grid for 4 weeks now, and 2 days ago I suddenly got unexplained Error codes 14.
- Everything has been working for 3 weeks: cooking, baking bread, making coffee, fridge...
- Suddenly 2 days ago the Multiplus raised error 14 with an AC load of approx. 2300W after 2 minutes. Error kept returning after recovery.
What I've tried:
- disconnecting the VE.bus cable on Multiplus and Cerbo side. Error 14 returned at Pac=2300W
- deleting all assistants (relay assistants)
- switching off- and on the multiplus.
After all this, the Multiplus worked fine for approx. 20hrs WITH the VE.bus cable connected, running the fridge and other low power loads.
- Next evening, running the electric grill at 2200W for a minute, error 14 returned, very occassionaly alternating with error code 5.
After trying all again, disconnecting VE.bus cable, removing all assistants... the error kept returning.
Now, after disconnecing the battery normal operation resumed. No VE.bus error with the original cabling and with all assistants enabled like before.
So it seems, error 14 came out of nowhere. My system is in a small space, having to disconnect cables during holidays to trouble shoot spurious errors on brand new expensive equipment is no fun at all.
Anyone else having the same/similar problem? And solution?
